England captain Robshaw will go toe to toe with British Lions and Wales skipper Sam Warburton on Sunday in what promises to be a titanic Twickenham clash.

Both sides are tied on four points at the top of the table after three games along with Ireland and France.

England are still scarred by their defeat to Wales last year that cost them a Grand Slam.

“They are a side who have beaten us and we haven’t beaten them,” said Robshaw. “But look at what is up for grabs – a Triple Crown for us and that’s massive. We haven’t had the chance of that kind of achievement before

on home soil.

“Then the winners potentially go for a Six Nations decider next week. You’re going to need a bit of luck somewhere but it sets it up very nicely.

“There’s too much at stake to worry about what has gone before.”

Robshaw admits Warburton is a formidable obstacle to their Triple Crown hopes.

“Sam is an incredible player - he’s shown that consistently over the last couple of years with how strong he is over the ball,” he said.

“He and Dan Lydiate work very well together - Dan with his chop-axe tackles that allow the next guy, normally Sam, to close in on the ball.

“We have to identify that threat and move them away from it.

“A lot of it comes from experience and understanding. The Welsh back row have played quite a few games together. But we are starting to develop that with England as well.”

When England head coach Stuart Lancaster confirms his selection today there will not be a single survivor of the line-up knocked out of the 2011 World Cup by France just over two years ago.

Wales will still have 11 of their 2011 semi-finalists - and 12 Lions to England’s two.

Robshaw refuses to dwell on the 30-13 thumping in Cardiff last year that saw England’s Grand Slam hopes dashed and handed the Six Nations title to Wales.

“I don’t think there’s any point in replaying last year’s game - but what it shows is what not to do,” he said.

“Of course people will remember what happened and probably always will. We have to be smarter with how we play.”

England will repeat their long walk through the fans from the team bus into Twickenham - with Robshaw claiming it helped fire-up his troops before their 13-10 win over Ireland a fortnight sgo.

He said: “You are always looking for an edge in every department, the small percentage here and there, and hopefully this will be one.

“As you walk down through the Lion Gate it’s a special moment that gets you in the zone.”
